Update: Replaced both fuel pumps, fuel filter, fuel pressure regulator, checked fuel accumulator, replaced crank position sensor. After 10 to 15 minutes of running it starts to miss and then stalls, will not restart for hours. It does have battery voltage to fuel pumps while stalling and cranking.
While dead it has spark at the plugs and power to the fuel pumps. Disconnected fuel line to fuel distributor, held thumb over line, cycled key and it sprayed gas. Tried starting fluid but still no fire?
This system has the fuel pump relay as part of the MAS. Are there other systems controlled by the MAS and OVP that can cause stall and no restart? Thanks
